Abstract: An absorbent for removing acid gases from a fluid flow comprises an aqueous solution of a) at least one amine and b) at least one phosphonic acid, wherein the molar ratio of b) to a) ranges between 0.0005 and 1.0. For example, the phosphonic acid is 1-hydroxyethane-1, 1-diphosphonic acid. Compared to absorbents based on amines or amine/promoter combinations, the absorbent requires less regeneration energy without substantially reducing the solution's capacity to absorb acid gases.
